A multi-zone solution designed for the realities of homes in Laval and Greater Montreal
At AirGreen , we have been installing multi-zone HVAC systems for many years in a wide variety of settings: single-family homes in Laval, multi-unit dwellings in Montreal, new condos on the South Shore, and complete renovations on the North Shore. The ELIOS E-MULTI 2-head heat pump with a 27,000 BTU compressor fits perfectly into this real-world situation: it meets a common need—efficiently heating and cooling two separate zones with a single outdoor unit—while maintaining excellent performance in cold climates.
This type of configuration is particularly sought after by homeowners who want to avoid multiple outdoor units , reduce visual and noise clutter, and achieve precise temperature control in each room. In Laval, where there are as many multigenerational homes as there are recent open-concept constructions, this system stands out for its genuine flexibility and consistent performance.
A truly flexible multi-zone architecture, designed for everyday comfort
The ELIOS E-MULTI heat pump is based on a simple yet extremely efficient design: a single outdoor compressor capable of powering up to two active indoor units , with the technical capability to expand to four zones depending on the building's overall configuration. In the 27,000 BTU version, we have ample power to serve two large living spaces without compromising thermal stability.
Wide selection of indoor units to suit building constraints
One of the tangible advantages we observe in the field concerns compatibility with several types of indoor units :
-
Wall-mounted units (6,000 to 24,000 BTU) for bedrooms, living rooms, or closed offices
-
Ducted units for discreet distribution in open spaces
-
1-way or 4-way cassettes for suspended ceilings
-
Brackets for specific configurations (low walls, finished basements)
In Laval, we recently installed this model in a two-story house where the ground floor required a 4-way cassette for even distribution, while the upper floor benefited from a quiet wall-mounted unit for the bedrooms. The same outdoor compressor provided consistent coverage throughout, without any imbalance between the zones.
Independent control and constant comfort
Each indoor unit operates with its own thermostat , allowing for precise adjustment based on the actual occupancy of each room. This avoids the common problems we see with poorly sized systems: overheating in one area, discomfort in another, or cycles that are too short or too long. Here, the modulation is gradual, stable, and perfectly suited to modern residential use.
Cold climate performance: a key factor for Quebec
A non-negotiable criterion for us at AirGreen remains heating capacity in real winter conditions . The ELIOS E-MULTI 27,000 BTU compressor is designed to operate efficiently down to -25°C , which corresponds to the winter temperatures we regularly experience in Laval, Montreal, and on the North Shore.
Power available even at low temperatures
In practice, this means:
-
27,000 BTU nominal air conditioning
-
In heating mode, a power output of around 18,000 to 19,000 BTU is still available at significantly negative temperatures.
-
Stable operation without excessive reliance on backup power sources
In particular, we replaced electric baseboard heaters in a Laval duplex with this system: even during the cold snaps of January, the heat pump maintained a constant indoor temperature without unpleasant fluctuations.
Measurable energy efficiency
The performance indicators are particularly high:
-
SEER2 greater than 23 in air conditioning
-
HSPF2 around 19.5 in heating
-
High COP even at -8°C , guaranteeing an excellent ratio between energy consumed and heat produced
These values translate directly into a tangible reduction in the electricity bill , especially when replacing resistive electrical systems or old air conditioners.
R-454B refrigerant: efficiency and environmental compliance
The ELIOS E-MULTI heat pump uses R-454B refrigerant , an important technological choice for the future of HVAC in Quebec . This gas has a lower global warming potential compared to previous generations, while maintaining excellent thermodynamic properties.
In practice, this means:
-
Compliance with current and future standards
-
Greater acceptability for grant programs
-
A more sustainable system in the long term
The system also incorporates leak detection devices , with automatic compressor shutdown and safety ventilation if necessary, a point often underestimated but essential for a modern residential installation.
Noise levels suitable for residential environments
In Laval's residential neighborhoods, noise is a recurring concern. The outdoor unit of this model has a noise level of around 61 dB(A) , which is very low for a 27,000 BTU multi-zone capacity. Indoors, some wall-mounted units reach around 20 dB(A) in low mode, a real advantage for bedrooms and home offices.
During a recent installation near Centropolis, the client was concerned about noise disturbances in the evening: after commissioning, the operation was barely perceptible inside, even during nighttime heating cycles.
Professional setup: a determining factor
A multi-zone system requires a rigorous HVAC installation , from sizing and piping to drainage and load balancing. At AirGreen , we manage the entire process:
-
Detailed thermal analysis
-
Optimal selection of internal heads
-
Strict adherence to pipe lengths and diameters
-
Controlled vacuuming and pressure testing
-
Fine-tuning of operating parameters
This approach allows us to fully exploit the potential of the ELIOS E-MULTI heat pump and avoid the problems we too often see in botched installations.
LogisVert subsidy and project profitability
This model is eligible for the LogisVert provincial grant , with an amount of up to $2,160 , subject to applicable conditions. We systematically assist our clients in Laval, Montreal, Longueuil, and the South Shore with the administrative procedures to secure this financial assistance.
In several recent projects, the combination of subsidies and energy savings has made it possible to recoup a significant portion of the investment in just a few years.

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 23,600 BTU/h at −8 °C, 19,000 at −15 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 2 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 13 combinations, from 6+6 to 18+18 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$2,832 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 3799027. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 20 dB(A). Outdoors, 61 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts; labour is not included by the manufacturer. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
